String str2 = "anand";
String str3 = "Ajeet";
String str4 = "Antrish";
// Calling equals method
System.out.println("Compare str1 and str2 with equals method===>" + str1.equals(str2));
System.out.println("Compare str1 and str3 with equals method===>" + str1.equals(str3));
System.out.println("Compare str3 and str4 with equals method===>" + str3.equals(str4));
//calling equals ignore method
System.out.println("Compare str1 and str2 with equalsIgnore method===>" + str1.equalsIgnoreCase(str2));
System.out.println("Compare str1 and str3 with equalsIgnore method===>" + str1.equalsIgnoreCase(str3));
System.out.println("Compare str3 and str4 with equalsIgnore method===>" + str3.equalsIgnoreCase(str4));
}
